Conditions at Isdhoo in September
September: Strong Shoulder Month
September retains much of the southwest monsoon's power. Ideal wind is 41%, with W (27%), WSW (22%), WNW (17%) and SW (10%) dominating the wind rose. Average swell stays at 4ft (1.3m), period 6.9s. The wave rose is still south-heavy - SSE (35%), S (24%), SSW (17%) and SW (13%) - but the system begins to lose a little intensity compared to August. For Isdhoo, that means continuing consistency but a slowly increasing chance of wind-affected surfaces as the monsoon starts to break down. Rain is active at 6.9mm/day, water temp 29.0°C. Still a good month, but you need to watch the daily wind pattern more carefully.
